Rotary switch setting

The rotary switch (REF AD) sets the refrigerant circuit address of the outdoor unit.
Confi gure the settings only on the master unit of a refrigerant system.
If multiple refrigerant systems are connected, set the rotary switch (REF AD) as
shown in the table below.

Pipe length set-
ting *1
00
Pipe length means the length between master outdoor unit and the nearest
indoor unit.
Sequential start
shift *1
10
The start-up timing of outdoor unit (compressor) can be set up so that it can
delay several seconds.
This feature is useful when multiple number of outdoor units are installed and
turned on at the same time to limit the starting current.

Switching between
batch stop or
emergency stop *1
This mode selects the pattern of the stop function to be operated by the exter-
•
nal input terminal (CN134).
• • Batch stop: The stop of all indoor units connected to same refrigerant system
20
due to input signal coming from CN134.
• Emergency stop: When emergency stop is actuated, the indoor unit does not
accept the operation command from the remote controller. On the other hand,
when the emergency stop is released (no input from CN134), the air condi-
tioner does not return to the original operation until the indoor unit is turned on
by the remote controller.
Snow falling
protection fan
mode *1
22
This mode operates the fans of outdoor units in order to prevent the units from stop-
ping operation when they are covered by snow.
Interval setting
for snow falling
protection fan
23
mode *1
When the snow falling protection fan mode is set, the operation interval of the fans
of outdoor units can be selected.
High static pressure
mode
24
When installing a duct to the blow-off outlet of an outdoor unit, set the high static
pressure mode according to the static pressure of the duct to be installed.
Furthermore, use this setting if the air blow of an outdoor unit is poor, such as when
installed in a place with a low ceiling.
